Various astronomical "shadow events" occur throughout the Solar System!  This month's more interesting ones are featured here.

SHADOW WORKS

Here we highlight (and set up) the most awe-inspiring eclipses taking place in our Solar System, so that all you need to do is click on their links.  Don't forget that you can generate lists of Earth's, Jupiter's, Saturn's, Uranus's, Neptune's and even Pluto's eclipses, using CELESTIA's own built-in "Eclipse Finder."  You'll find it in the program's menu under "Navigation".

All events listed below are displayed as if viewed from Earth, their magnifications shown in parentheses at the lower right of CELESTIA's window.  Events involving more than one moon are often cyclical, so usually only the first example is given, and then the period of the cycle.

JUPITER

Simultaneous solar eclipses on Jupiter are again a "no show" in June.  Io, Europa, Ganymede and Callisto—the "Galilean" moons—are still "spread out" in their orbits this month.  So the highlights of the 31 solar eclipses they produce are less spectacular than those in other months.  Notice that Jupiter's shadow still stretches off to the west (right on your screen,) and examples of the Galileans moving in and out of it are also included.

• June 2: having cast its own shadow hours before, Io passes Europa as that moon enters Jupiter's shadow; this cycle repeats about every 3½ days;  (1.6.x)   (1.4.1)
• June 2: Ganymede casts its shadow, and Io moves into Jupiter's shadow in a cycle that repeats about every 7 days;  (1.6.x)   (1.4.1)
• June 6: Io moves into Jupiter's shadow, then more distant Ganymede emerges from it in another 7-day cycle; and shows how much Jupiter's shadow stretches off to the right  (1.6.x)   (1.4.1)
• June 7: Io casts its shadow on Jupiter and joins Callisto in transiting their parent at the same time  (1.6.x)   (1.4.1)
• June 23: continuing the June 2 cycle, Io passes Europa, which enters Jupiter's shadow just before Callisto casts its shadow near Jupiter's south pole  (1.6.x)   (1.4.1)
• June 24: a nice view of three major moons near Jupiter  (1.6.x)   (1.4.1)

SATURN

While CELESTIA 1.6.x shows the shadows of Titan, Rhea, Iapetus, Dione and Tethys, version 1.4.1 displays only the shadows of Titan, Rhea & Iapetus.  So, 1.6.x and 1.4.1 respectively show 34 and 7 solar eclipses on Saturn in June.  The highlights are as follows:

• June 1: Tethys casts its shadow on Saturn, as it currently does about every 2 days  (1.6.x only)
• June 2: Dione casts its shadow on Saturn, as it currently does about every 2¾ days; Titan transits Saturn but does not cast its shadow  (1.6.x)
• June 3: Rhea and Tethys cast their shadows on Saturn simultaneously (though 1.41 only shows Rhea's shadow); Rhea will continue to cast its shadow about every 4½ days  (1.6.x)   (1.4.1)
• June 10: Rhea emerges from Saturn's shadow; Dione casts its shadow; Titan emerges from behind Saturn  (1.6.x only)
• June 18: Tethys and Dione cast their shadows on Saturn simultaneously  (1.6.x only)
• June 26: Rhea and Tethys cast their shadows on Saturn simultaneously, and Titan moves behind Saturn  (1.6.x only)

URANUS, NEPTUNE & Dwarf Planet PLUTO

Neither Uranus nor Neptune will experience eclipses for decades.  Dwarf planet Pluto will experience no eclipses by Charon for about a century!
